NY. Application November 15, 1957, Serial No. 696,649 3 Claims. Cl. 229-28 This invention relates to cartons, and more particularly to those of the type especially adapted for containing 7 eggs, fruits, vegetables or many other kinds of goods, and particularly goods likely to be broken or damaged during shipping, handling or storage.

Various kinds of protective cartons have been proposed for containing eggs, for example, and most of them fail to provide maximum protection for the goods, .with the result that many eggs are broken in transit, in handling, A great deal of'breakage of these goods follows from the fact that injsome of the egg cartons the eggs are not properly maintained in spaced relation nor cushioned in a manner to protect them against shocks and jars to which the cartons are often subjected. In addition, many storekeepers stack the egg-containing cartons one upon the other and since I in most cartons, little or no provisionis made to firmly support the covers of the cartons and prevent them from collapsing or exerting excessive downward pressure on the eggs, such cartons when stacked, often partially collapse, resulting in breakage of their contents.

It is.an object of the present invention to ,provide a carton which, while primarily intended for containing eggs, can be used for many other globular or rounded articles, and which, because of its construction, provides a maximum of protection and resistanceto damage or breakage of its contents. W C I It 'is an objectof the-inventionto -provide a'carton which shall provide a novel cushioningmeans for the eggs or other articles, and which cushioning means will adapt itself to eggs of various sizes; which will act to resiliently engage the eggs to hold the same gently but firmly against shifting in the carton; which will'maintain the eggs in separated relation and tend to absorb shocks and thus afford a maximum of protection forthe goods.

It is another object of the invention to provide in a carton of this charactena stilfeningand reinforcing element, consisting of a plurality of contiguous plies of cardboard, arranged centrally and longitudinally of .the

carton as a stilfeningspine and acting as a partitioning member of such height that it rises above the tops of the eggs and supports the cover of the carton in such a manner that the cartons can-be stackedpone upon. another without fear of collapse 'of anyof them in thestack.

It is an object of'the invention to provide acarton as above-described which shall preferably be composed of a single section or blank of cardboard; which can be easily fabricated and set up and which will provide a rigid protective structure for its contents.

With these and other objects to be hereinafter set forth in view, I have'devised the arrangement of parts to be described and more particularly pointed'out in i the claims appended hereto. i

1 structed, is shown in Fig. 1, wherein it will be noted that the ,same preferably consists of a single lengthy 'strip, the width thereof depending upon the number of eggs or other articles to be contained in the carton. The cover of the carton is shown at 1, the forward edge thereof being defined by the fold or score line 2 and the rear fold or hinge line being the score line 3. The cover locking flap is shown at 4 and the same is provided with a number of tabs 5, some or all of which may be of the hooked form shown. At '6 is shown the rear wall of the carton, the same being located between the score line 3 and a bottom score or fold line indicated at 7. One of the bottom wall sections is shown at 8, the same being located between the score line 7 and a parallel score line 9 which is interrupted at intervals by stamped-out tabs 10 which cooperate with similar tabs shown at 11, in form- 1 ing central supporting feet for the bottom of the carton,

as shown inFigs. 3 and 6.

The part of the blank shown at 12, and located between the score lines 9 and 13, forms one of the walls or panels of a central partition member which divides the carton into two longitudinal channels in which the eggs or other articles are contained. A co-operating is shown at 14, the same'being The score line 13 is interrupted by the formation, of a stamped-out tongue 16 adapted, when the carton is in its erected form, to extend upwardly from the score line 13 and form a central ply for the upper portion ofthe partition 1 in a manner to be explained.

The second bottom wall section of the carton is shown at 17 and the same is located between thefscore line 15 and 'a score line shown at 18, the latter score line being :cated at 24 and 26.

located at the front lower end of the .carton as" shown in Figs. 2 and 3. The front wall of the carton'j is shownat -19, the same being located betweenjthe score line 18 and One of the slitted top panels is shown at 21, the same being located betweenthe'fold or score line 20 and a score line shownat 22. Beyond the score line 22 is a narrow area 23 constituting one of the outer and upper walls of thecentral partition, this area being located between the score line 22' and that shown at 24. A similar strip portion '25 forms the secondupper and outer wall of the central partition," this strip portion being located between'the .scoreilines indi- The secondsection of the top wall, of the carton is shown at 27, the same being similar to that shown. at 21', and being located between the score lines 26 and .28. Beyond the score line 28 is shown the attaching flap 38 which, when the carton is in its folded position, is adas clearly seen in Fig. 4.

Each of the top panel sections is longitudinally and hesively attached to the inside face of therear wall'6 'interruptedly slit as shown at 30 and 31, and. these slits are connected by the transverse slits shown at 32. Betweenthe slits 32 and extending parallel thereto are shorter slits 3,3. and at the opposite ends of the slits 33 are divergent extensions' 34 from the ends of,' which'score lines 35 extend angularly and divergently reformer.

thereby by its front and rear ends as well as by the meet- 3 angulated elements shown at 36; At the ends of the carton are formed score lines 37, co-operating with parts of the slits 30, 31 and, 32 to form downwardly-foldable flaps 39. The described arrangement is such that the slits formed as above described, result in the production of flap elements which folddownwardly on the fold lines 35 and break or separate on the slits 33, 34.

In Figs. 2 and 3, the manner in which the blank of 'Fig. 1 is folded'and secured is shown. It will be noted that when folded as clearly seen in Fig. 2, the attaching flap 38 comes into position to permit of it being adhesively or otherwise attached to the rear wall 7, as shown in Fig. 3. It will be observed that the partition panels 12 and 14 extend upwardly Within the carton body, and that the tongue 16 projects upwardly above the upper junction of these two partition panels. Accordingly, the tongue 16 becomes located between the two upwardly-directed and connected upper partition panels 23 and 25. This tongue portion may be adhesively secured between the two upper parts 23 and 25 and the three parts 16, 23 and 25 may be stapled or otherwise fastened together, resulting in a central partition or lengthy stiffening spine, extending down the carton for its entire length, and which spine is of exceptional strength and stiffness, and particularly in its upper, three-ply area. As will be seen in Fig. 3, the rear wall 6 of the carton is of substantially the same height as the central partition, sothat when the cover is closed down, as seen in Fig. 3, it will rest upon and be supported by the upper end of the partition. As will be seen in Fig. 5, the central partition is preferably higher than the eggs 45 or other articles to be contained in the carton. Therefore, the firm support of the cover by the central, upstanding partition of exceptional rigidity and strength, insures the avoidance of pressure on the eggs or other contained articles, or the collapse or partial collapse of the cover even when a substantial number of the filled cartons are placed on top of one another in stacked relation. 1 a

The construction of the egg-receiving compartmentsis clear from Figs. 4 and 5 wherein it will be noted that the eggs or other rounded articles are each engaged between two of the flaps 40, 40 or 39, 40. When an egg or other article is pressed lightly down on two of the adjacent flaps, the flaps will fold downwardly on the slits 33, 34 and on the score lines 35, to allow the egg to enter into its compartment. The tendency of the two flaps to' riseto horizontal position, causes them to lightly, but securely, and in a cushioned manner, embrace the egg between them as seen in Fig. 5, and this tendency also causes each co-operating pair of flaps to adjust themselves to eggs or other articles of varying sizes. The formation of the slits 33, with Y-shaped ends, enables the flaps formed by these slits and co-operating slit portions 31 and 32, to assume a curvature somewhat similar to the surface curvature of the egg or other rounded object, and the production of this curvature in the flaps can be facilitated by the use of light scorings in the flaps as indicated at 47 in the blank shown in Fig. 1.

From the foregoing, the construction and use of the improved carton will be readily understood. The carton in its folded and glued form, as in 'Fig. '3, can be col- When erected it being supported ing tabs 9 and .11, which form central supporting legs, as clearly seen in Fig. 3. .The eggs or other rounded objects placed in the carton are firmly engaged by the flaps 39 and 40 yet are cushioned by theiriresilient engagement between these flaps. The eggs in the two rows are wholly separated from one another by a relatively high central partition which is two-ply in its lower area and three-ply in its upper portion, thereby providing in such upper portion, wherein stilfness and rigidity is required, exceptional strength to resist collapse of the cover and thus holding the cover raised and free from contact with the eggs in the carton.

The triangulated ends 36 on the flaps 40 lend stiffness and rigidity to the carton; the eggs are kept separated and protected against breakage, which effort is further aided by the elevation of the greater portion of the bottom walls 8 and 17 of the carton from contact with any support on which the carton may be rested.

Having described a single embodiment of the invention, it is obvious that the same is'not to be restricted thereto,

. but is broad enough to cover all structures coming within the scope of the annexed claims.
